Development and Test of a Crash Experimental System of the Level Ejection Type Automobile Bumper

Based on the analysis of automobile bumper crash, and combined with the features of the bumper absorbing energy, a rig for bumper crash test was developed. The rig has advanced features of small size, wide-range of usage and arbitrary movement. The frontal and side crash can be tested according to different models and materials, and, hence, to provide a viable test method to study the general crash performance and energy absorption situation of the bumper, and reliable test data for investigation of automotive passive safety. In this paper, the structure and design of the rig is presented fist, followed by the working principles of the experiment system and theoretical analysis of the experimental process. An experiment was conducted which proved the successful development of the experimental system.
